Summary: A new sobemovirus, which we have named "mimosa mosaic virus" (MimMV), was found by high-throughput sequencing and isolated from a mimosa (Mimosa sensitiva L.) plant. The genome sequence was confirmed by Sanger sequencing and comprises 4595 nucleotides. Phylogenetic analysis based on the predicted amino acid (aa) sequences of the P2b protein (encoded by ORF2b) and the coat protein showed 52.7% and 31.8% aa sequence identity, respectively, to those of blueberry shoestring virus. The complete genome sequence of MimMV was less than 47% identical to those of other sobemoviruses. These data suggest that MimMV is a member of a new species in the genus Sobemovirus, for which the binomial name ?Sobemovirus mimosae? is proposed.
